Enter the date of death and get every date for the chūin services (Shonanoka, Futanoka to Munanoka, the 49th day), the 100th day, and the annual memorials (1st, 3rd, 7th, 13th, 17th, 23rd, 25th, 27th, 33rd, 37th and 50th), with weekday, rokuyō and Japanese era. You can switch between the nationwide counting (the day of death is day 1) and the counting used in parts of Kansai (the day before is day 1, otaiya), and it also shows the nearest weekend or holiday before each date for moving a service earlier. It checks whether the 49th day spans three months (mitsuki-matagi), whether the first Obon (Hatsubon) is this year or next, and calculates kyōnen (age by Japanese reckoning) and gyōnen (full age). It also includes a year-by-year memorial quick reference and a feature that lines up a family's memorials by year to find overlapping years (candidates for combined services). Schedules can be copied or added to a calendar (.ics).

The 49th day falls under “mitsuki-matagi” (spanning three months)
Death in month 3 puts the 49th day (5/2/2026 (Sat)) into the third month. Because of a pun (shijūku “49” sounds like “suffering”, mitsuki “3 months” sounds like “it sticks”), some regions move the end of mourning up to the 35th day (4/18/2026 (Sat)). It is a superstition and many regions and temples ignore it, so the surest way is to consult your family temple.
Chūin services (7th–49th day) and the 100th day
Counted every 7 days with the day of death as day 1 (the 7th day is 6 days after death, the 49th day is 48 days after).

Kyōnen and gyōnen calculation

Enter a date of birth above to calculate kyōnen (Japanese reckoning) and gyōnen (full age).
Annual memorial quick reference (2026, 2027)

ABOUT
About Buddhist Memorial Service Calculator | 49th Day, Shonanoka to Hyakkanichi, 1st/3rd/7th Memorial Dates and Annual Memorial Chart
The Memorial Service Calculator lists, from nothing more than the date of death, the chūin services up to the 49th day and the annual memorials such as the 1st-year and 3rd memorials. Chūin services are counted every 7 days with the day of death as day 1: the 7th day (Shonanoka) is 6 days after death, the 35th day (Itsunanoka) is 34 days after, the 49th day (Nanananoka) is 48 days after, and the 100th day (Hyakkanichi) is 99 days after. You can also switch to the counting used in parts of Kansai, where the day before death is day 1 (counting from otaiya, the eve). For annual memorials only the 1st-year memorial (Isshūki) is exactly 1 year; from the 3rd memorial (Sankaiki) the year of death counts as 1, so the 3rd is after 2 years, the 7th after 6 years, the 13th after 12 years and the 33rd after 32 years. Each date comes with the weekday, rokuyō and Japanese era, plus the nearest weekend or holiday before it for when you move a service earlier. The tool also checks whether the 49th day spans three months from the month of death (mitsuki-matagi), whether the first Obon (Hatsubon) that follows the end of the 49th day is this year or next, and calculates kyōnen (age by Japanese reckoning) and gyōnen (full age) for the mortuary tablet and grave inscription. In addition there is an annual memorial chart showing which memorial falls in a given year for people who died in each year, and a feature that finds years when the memorials of several family members overlap (candidates for combined services).

Good to know
- Chūin services are generally counted nationwide with the day of death as day 1. In parts of Kansai the day before death is day 1, and the service may be held the evening before (otaiya). Follow the custom of your family temple or region.
- For annual memorials only the 1st-year memorial is exactly 1 year; from the 3rd memorial the year of death counts as 1 (3rd memorial = 2 years after). Note that the 3rd memorial is not 3 years later.
- A service does not have to be held on the actual death anniversary (shōtsuki meinichi), but it is generally moved earlier, not later. The “nearest weekend/holiday before” column shows weekends and holidays on or before the date.
- The 25th and 37th memorials are not held in some sects and regions. Tomurai-age (the last annual memorial) is often the 33rd or the 50th memorial.
- Mitsuki-matagi is a custom that comes from a pun and has no firm basis. Many regions and temples ignore it, so consult your family temple before deciding.
- The first Obon (Hatsubon) is the first Obon after the end of mourning on the 49th day. This tool treats it as this year if the 49th day ends before the start of Obon (the 13th), and next year otherwise.
- Kyōnen is generally written by Japanese reckoning (the birth year counts as age 1, +1 every New Year's Day) and gyōnen as full age, but some regions and temples write kyōnen as full age.
- Rokuyō is a guide calculated from the old lunar calendar. Services are said not to need to care about rokuyō, but treat it as a reference according to your relatives' views.
- If death was on February 29, the anniversary in non-leap years is shown as February 28.

FAQ
- How do I count the 49th day?
- Count the day of death as day 1; day 49 is the 49th day (Nanananoka), which is 48 days after the date of death. For example, if someone died on March 15, 2026, the 49th day is Saturday, May 2, 2026. In parts of Kansai the day before death is day 1, so it is one day earlier, May 1.
- How many years after death is the 3rd memorial?
- After 2 full years, that is, the year after the 1st-year memorial. Only the 1st-year memorial is exactly 1 year; from the 3rd memorial the year of death counts as 1, so a memorial falls “memorial number − 1” years after death. The 7th memorial is after 6 years, the 13th after 12 years and the 33rd after 32 years.
- What is mitsuki-matagi?
- It is when the 49th day reaches the third month counting from the month of death. A pun on “shijūku” (49, sounds like “suffering”) and “mitsuki” (3 months, sounds like “it sticks”) makes it seen as unlucky, so in some regions mourning ends early on the 35th day. With the counting where the day of death is day 1, death from roughly the 14th of the month onward (the 12th for January and February, the 15th for July and December) spans three months. It is a superstition and many temples ignore it, so consulting your family temple is the surest way.
- Is the first Obon (Hatsubon) this year or next year?
- The first Obon is the first Obon after the end of mourning on the 49th day. For the August Obon (13th–16th), if the 49th day ends before August 13 it is that year; otherwise it is the following year. As a rule of thumb, death before about June 25 means this year, and later means next year.
- Which memorials fall in 2026, and for people who died in which years?
- In 2026 (Reiwa 8) it is the 1st-year memorial for those who died in 2025, the 3rd for 2024, the 7th for 2020, the 13th for 2014, the 17th for 2010, the 23rd for 2004, the 25th for 2002, the 27th for 2000 and the 33rd for 1994. You can check other years in the tool's annual memorial chart.
- What is the difference between kyōnen and gyōnen?
- Kyōnen is generally written by Japanese reckoning (the birth year counts as age 1, +1 every New Year's Day) and gyōnen as full age. For example, for someone born on May 1, 1940 who died on March 15, 2026, kyōnen is 87 and gyōnen is 85. Some regions and temples write kyōnen as full age, though.
