Chinese Calendar May 2027: Lunar Dates, Day Officers and Auspicious Days
31 days · Start of Summer and Grain Buds · 2 wedding dates, 2 for moving house and 4 for opening a business
May 2027 has 31 days in the Gregorian calendar, and the Chinese calendar cuts them twice over. The lunar calendar runs lunar month 3 (三月) from 1 May 2027 to 5 May 2027 and lunar month 4 (四月) from 6 May 2027 to 31 May 2027. The solar half of the same system — the one the almanac uses to set each day's pillar — hands the month over from the Dragon month 甲辰 to the Snake month 乙巳 at Start of Summer (立夏) on 6 May 2027, 01:25 (Beijing time, UTC+8).
Two solar terms fall in May 2027: Start of Summer (立夏) on 6 May 2027, 01:25 (Beijing time, UTC+8) and Grain Buds (小满) on 21 May 2027, 14:18 (Beijing time, UTC+8). The almanac (通书 / 黄历) entry for each of the 31 days in the table below carries its own stem-branch day pillar, one of the twelve Day Officers, the animal the day clashes with, and the activities the classical tables mark as favourable.
All 31 days belong to the 丁未 Fire Goat year, which began at Lichun, 4 Feb 2027, 09:46 (Beijing time, UTC+8). Days whose branch clashes with the year branch 未 are Sui Po (Year Breaker) days and are struck out of every list below — in May that is 10 May 2027 (己丑) and 22 May 2027 (辛丑).
Under the strict reading used on this site — Day Officer Stable, Success or Open, the activity listed as favourable and not as unfavourable, no Sui Po day and no four-separation day — May 2027 has 2 wedding dates, 2 for moving house and 4 for opening a business. 6 of the 31 days carry a Destruction or Danger officer or are Year Breaker days, and are listed further down as days to take slowly.

The Day Officer (建除十二神) is counted from the solar month's branch: the day whose branch matches the month's is Establish (建), and the twelve run in order from there. Days up to 2027-05-05 are counted from the Dragon month 甲辰, the rest from the Snake month 乙巳.

Days to take slowly in May 2027
Two rules put a day on this list: a Day Officer of Destruction (破) or Danger (危) — the two the classical tables rate lowest for starting anything — and the Year Breaker (岁破) days, whose branch clashes with the year branch. Nothing here is forbidden; the tradition is to keep such days for maintenance, clearing out and repairs rather than for beginnings.
| Date | Day pillar | Day Officer | Why it is on this list |
|---|---|---|---|
| 2027-05-08 Sat | 丁亥 | 破 Destruction (Po) | Destruction officer |
| 2027-05-09 Sun | 戊子 | 危 Danger (Wei) | Danger officer |
| 2027-05-10 Mon | 己丑 | 成 Success (Cheng) | Year Breaker — clashes with the year branch |
| 2027-05-20 Thu | 己亥 | 破 Destruction (Po) | Destruction officer |
| 2027-05-21 Fri | 庚子 | 危 Danger (Wei) | Danger officer |
| 2027-05-22 Sat | 辛丑 | 成 Success (Cheng) | Year Breaker — clashes with the year branch |

Frequently asked questions
- How many auspicious days does the Chinese almanac give for May 2027?
- 2 wedding dates, 2 for moving house and 4 for opening a business — 8 entries across the three events, out of 31 days. Each date has to clear the Day Officer filter, the almanac's own favourable list, the Year Breaker and the four-separation days. A day can qualify for more than one event, so the three lists overlap.
- What do the solar terms in May 2027 mark?
- Start of Summer (立夏) arrives on 6 May 2027, 01:25 (Beijing time, UTC+8) and Grain Buds (小满) on 21 May 2027, 14:18 (Beijing time, UTC+8). The first of the two is a "Jie" term: it starts a new solar month, so from that moment the day pillars are counted from the Snake month 乙巳 instead of the Dragon month 甲辰. May 2027 carries no traditional festival, which is why the day table below shows solar terms only.
- Why is 5 May 2027 excluded even though its Day Officer looks fine?
- It is a four-separation day (四离四绝): the day immediately before Start of Summer (立夏), which arrives on 6 May 2027, 01:25 (Beijing time, UTC+8). The classical rule is that the old season's energy is spent and the new one has not begun, so weddings and major moves are held over. May 2027 has one such day, and it is this filter — not the Day Officer — that keeps it out of the three lists above.
